Title: Method for manufacturing chip electronic component
Inventor: OKIMOTO TOMOHISA
IPC: H01C1/14
Filed: 1996-01-26
Abstract: PROBLEM TO BE SOLVED: To remove a metal film adhered to an element portion of a chip and form a metal layer excellent in wetness for solder on a terminal electrode by a method wherein, after a metal film excellent in wetness for solder is formed on the entire face of a chip, the metal film is heated and melted at a melting point or higher in vapor or liquid. SOLUTION: A terminal electrode 4 is formed in a dip type on both end faces of an element 1, and on the faces by plating, a metal film (solder film) 3 excellent in solder wetness is formed on the entire face of the element 1 and the terminal electrode 4. Next, the metal film 3 is heated and melted and alloyed with an underlayer metal on a face of the terminal electrode 4 to form a metal layer 5 excellent in solder wetness, and it gathers to the side of the terminal electrode 4 by a surface stress of the molten metal on the face of the element 1. Alternatively, it becomes metal balls and drops by its weight while cooled and solidified. After cooled, the metal balls formed on the face of the element 1 are removed by ultrasonic cleaning. Thereby, it is possible to form the metal layer 5 excellent in solder wetness on the face of the element 1 only in the terminal electrode 4 without peculiar coating.

Title: Speed control method for unmanned vehicle
Inventor: OKURA AKIRA
IPC: B60L15/20
Filed: 1988-01-21
Abstract: PURPOSE:To perform highly accurate speed control through reduction of measurement errors of travel distance and to prevent runaway due to malfunction of machinery, by detecting travel pulses produced from a pulse generator then performing speed control based on the number of detected pulses. CONSTITUTION:Upon start of travel control program, measurement through a pulse counter (Pc) 12 and an encoder (Re) 19 is started at a very low speed in step (Stp) 1. Conversion to normal travel mode is made in Stp 2, and resolution of a pulse signal fed from Re 19 is lowered to the same level as that of the pulse signal fed from the Pc 12. It is checked whether or not travel through a predetermined distance necessary for comparison of both travel pulse signals is finished, and if the answer is 'NO', the process goes to Stp 6, while when the travel is finished, the process goes to Stp 3 where the number of both travel signals are compared. Travel is stopped, in Stp 5, if the difference between both travel pulses exceeds over a predetermined range, while when the difference is within the predetermined range, super low speed travel is continued and the process goes to Stp 6. Low speed travel mode is resumed in Stp 5 then the process returns to Stp 1, and the processes are repeated.

Abstract: PURPOSE:To prevent a transducer mounting means and a storage medium from the contact by approaching a rigid structure support contact part onto a plane formed by the floating face of the transducer mounting means. CONSTITUTION:A slider 20 being the transducer mounting means is fixed to the slider fitting part 16 by an adhesives or the like.
